Reviewing BAR modified AC45 Turbo (or 'T2' as they call it) looks, it really looks like a Lockheed Martin F-22 Raptor Stealth fighter.
To continue learning and understanding shapes & designs I'm currently drawing Oracle AC Turbo and will continue with this beauty above. BAR also used a different design for their foils compared to Oracle, while Artemis months ago had a new version of their stepped foils first used at past SF Cup for their first foiling 45. I will try to get a cad shape version of the three of them too.
